/* ========================================================
   Slot games styles
   --------------------------------------------------------
   Perf notes (rewrite):
   - Reel cell height is a CSS variable (--cell-h) so a single
     @keyframes reelSpin drives every size and variant. Four
     duplicated keyframe blocks collapsed into one.
   - drop-shadow on cells is disabled during the spin animation:
     you don't see the glow on blur-fast cells, and drop-shadow
     is one of the pricier filters to re-rasterize every frame.
   - .spin-btn::before sheen animates transform (composited)
     instead of `left` (which triggers layout per frame).
   - .machine and .reel use `contain: layout paint` — browser
     can treat their subtree as independent, no outside ripple.
   - .reel__strip has both will-change: transform and a
     translateZ(0) to guarantee an own compositor layer on
     older WebKit.
   - Numeric HUD/paytable values use tabular-nums so digit
     width doesn't jitter between spins.
